The most perverse moment on R. Kelly’s latest album is, surprisingly, neither “The Zoo” โ€” a slow-jam full of animal noises that suggests he and his lady had some company in the sack โ€” nor “Sex Planet,” which offers a particularly unfortunate metaphor for back-door action. It’s “Rise Up,” the product of Kelly’s belief that he could โ€” just days after the Virginia Tech massacre โ€” help the healing process by penning a carbon copy of “I Believe I Can Fly.” The result is a limp, quasi-gospel tribute to the victims’ families that needs tragedy to invest its clichรฉs with any sense of meaning. However, if you can overlook the disturbing sexscapades of a guy who still faces child pornography charges โ€” as well as Kelly’s tasteless tribute โ€” there are some worthwhile moments here. “Same Girl,” his long-awaited duet with Usher, is an understated, funny and hugely successful variation on “The Girl Is Mine.” Sure, the decision to focus on the clubs instead of the boudoir โ€” as exemplified by tracks such as the defiant dance anthem “Rollin'” โ€” may alienate some fans, but anyone who’s stuck with Kelly through his more serious travails can also make it through the overall disappointment that is Double Up.
